AIR CONDITIONING APPARATUS Application filed August 28', 1930. Serial No. 477,375.

My invention relates more particularly to apparatus .for the cleaning of air and the changing'of the moisture content and tem 0 for the general purpose above stated.

Another object is to provide apparatus of the general character above referred to which will operate with greater efiiciency than structures as hitherto provided Another object is to rovide an apparatus which may be utilized uring warm weather to cool, and preferably to remove excess moisture from, the air before supplying it to the rooms and may be utilized in cold weather to heat and humidify the air prior-to supplying it to the rooms.

Another object is to provide in an apparatus employing a power-operated air-forcing device, such as an electric fan, for the relatively free circulation of the air. through the conditioning apparatus with the minimum likelihood of undesirable leakage of water, and the entraining of the moisture in such finely divided condition as not to produce objectionable collection of drops of water on objects in the room; and other 0bjects'as will be manifest from the following description.

Figure 8 is avertical. sectional view taken at the irregular line 88on Fig. 7 and viewed tional, of a portable air conditioner embody- 7 ing my invention the-section being taken at the line 11 on Fig. 12. and viewedin the direction of the arrow; and

Fi re 12, a section taken at the line 12 on Fig.11, and viewed in the direction of the arrow.

Referring to the apparatus illustrated in Figs. 1 to 6, inclusive, 13 and 14 represent a being located at the insideof the space to receive the air conditioned by my invention and containing a lower openin 15 therethrough .which would be locate above the floor of said space, as for example about three feet above the floor, and an upper opening 16.

The lower opening 15 is provided with agrid-like door 17 shown as hinged at 18 to a frame 19 positioned in the opening the upper opening 16 is provided wit a gridlike plate-20' in t e form of a register.

Located in the space between the walls 13 and 14 is a sheet metal'casing 21 forming a conduit, its upper end, which'is open, being 15 and ister 20, a vertical series of substantially horizontally-disposed vertically-spaced eliminating plates 22 for intercepting entrained large drops of water should such be carried up with i the air.

The lower portion of the rear wall of the conduit 21 is forwardly curved as represented at 23, its front edge terminating in a substantially vertically extending portion 24, the portions 23 and 24 being of substantially the same width as the conduit 21 and forming a trough through the bottom of which adrain pipe 25 opens.

The front wall of the conduit 21 is shown as formed of two sections 25 and 26, the section 25 being of the full width of the conduit 21. The section 21 terminates at its lower edge adjacent the upper ed e of the opening 15 and is deflected rearwar ly as represented at 27 to afford a rearwardly offset flange. The section 26, forming a continuation of the section 25, is hinged thereto as represented at 28 and is downwardly and rearwardly curved as shown terminating at its rear portion in an upwardly-extending lip-portion 29. The section 26, which thus forms a trough, is preferably spaced at its ends a slight distance from the sides of the conduit 21 as shown in Fig. 5 when it extends horizontally as shown. The trough 26, however,

may be inclined from one end to the other in which case it need not be spaced at both ends from the conduit.

Mounted on the door 17, by a bracket 17, is an air forcing device shown as in the form of an electric motor 30, the armature shaft of which carries a fan propeller 31, the axis of the fan being shown as extending slightly below the lowermost portion of the trough 26. The fan serves to draw air through the opening 15 in the wall 13 and force it into the lower end of the conduit 21 through which the air'up'wardly flows discharging through the register 20 into the room.

Mounted on brackets 32 and 33 in the con duit 21 is a vertically disposed pipe-coil 34 comprising substantially horizontally disposed pipe portions 35 arranged in staggered position in a vertical series, the ends of the pipe sections 35 being connected together by cross pipes 36 disposed alternately at opposite sides of the pipe coil 34.

In the construction shown the mounting of the pipe coil 34 on the brackets 32 and 33 is at the lower and upper ones, respectively, of the horizontal pipes 35. i

The pipes 35 are each provided with a hori zontal series of spaced apart disk-like members 37 which form radiating fins.

Each of the alternate ones of the horizontal pipes 35 supports a trough 38 which extends crosswise of the conduit 21, these troughs being connected with the pipes 35 as by soldering them thereto, portions of the fins 37 on the pipes 35 equipped with the troughs 38 being cut away as represented so that they will conform at their edges with the undersides of the troughs and preferably be in thermahconducting relation thereto, being soldered to the troughs if desired.

The troughs 38, shown as connectedwith alternate ones of the pipes 35, are disposed in a general upright series but preferably are arranged in staggered relation as represented in Fig. 3, each successive one of these troughs being of less width than the one below it as shown in Fig. 2so that the watersupplied to these troughs, as hereinafter described and discharging from the ends thereof, will fall from one to the other of the troughs of the series thereof. In other words, the waterv will cascade from the uppermost trough to the one next below it and from the last referred-to trough to the third from the top and from the latter to the lowermost trough. The troughs 38 are closed at their opposite ends as indicated at 39 whereby the cascading referred to results from the overflowing of the water from these troughs.

Extending across the series of troughs 38 at their forward edges to span the vertical spaces therebetween, and of a width equal to the length of the troughs 38' is a member 40 of wire mesh which is in contact with the front edges of the trough and which is supplied With Water overflowing the troughs 38 at their front edges, the member 40 being in contact with the fins on the forwardmost ones of the pipe sections 35 and preferably soldered thereto.

The pipe coil 34 is connected at its upper end with a pipe 41 which leads from any suitable source of heating medium, as for example, steam under pressure, when the apparatus is to be used during cold weather for the heating and huniidifying of the air discharging through the register 20, and leads from a source of cooling medium, such as cold water or refrigerating fluid, when the apparatus is to be used in warm weather for cooling, or cooling and dehydrating, the air supplied through the register 20, the lower end of the coil 34 connecting with a pipe 42 through which the steam, or water, as the case may be, discharges from the coil 34.

Located in the conduit 21 is an upwardly extending pipe 43 terminating at its upper end in horizontally spaced branch outlets 44 located directly above the uppermost ones of the troughs 38 adjacent the opposite ends of the latter, the pipe 43 being provided for the purpose of conducting into the uppermost trough 38 for flow therefrom successively into the troughs 38 below it and for flow downwardly over the member 40, hot water in'the use of the apparatus during cold weather and cold water during warm weather. The lower end of the pipe 43 opens into a passage 44 in a valve casing 45 proa chamber 48 divided by a screen partition vided with a needle valve 46 which controls the flow through the passage 44,'the passagev 44 leading from a strainer device 47 having 49. The passage 44 opens into the chamber 48 on one side of the screen 49, and-the cham-' a source of hot water or cold water, as the case ma be. The stem of valve 46 extends outwar ly through one of the opposing grid members 17 as shown to permit of the manipulation of this valve from a point exterior of the member 17.

The wall section 26 of the conduit 21 is shown as releasably held in theposition illustrated in Fig. 3 in which it serves to receive such of the water as may overflow from the lowermost trough 38and drops from the lower edge of the screen member 40, the water thus flowing in the trough 29 flowing along this trough to its lower end where it discharges at the side of the conduit 2! into the trough'formed of the portions 23 and 24 of the conduit 21 and thence flows out through the pipe 25. I

As willbe understood from the foregoing description, the flow of air into the lower end of the conduit 21 and produced b the fan 31 moves crosswise of and beneath t e trough 26 thence rises in the conduit 21 in which it spreads out and is subjected to the heat of t e coil 34 and of the hot water in the troughs 38 and on the screen member 40, in the use of the apparatus in cold weather; and to the cooling effect of the coils and the cooling medium sup lied to the members 38 and 40 in the use oi the apparatus in hot weather. The provision of t e trough member 36 insures the travel of the air out of contact with the water discharging from the lowermost trou h 38 and the member 40, resulting in avoiding the carryin up in the air currents of water in relative y objectionable, large, particles.

The motor 30be'ing carried. by the swinging door 17 and the trough portion 26 being movable forwardly, by'swmgi-ng it at its hinge connection 28 with the 'conduit 'wallsection 25, the parts of the apparatus which would otherwise becovered-up are rendered accessible for cleaning or repair, the trough 26 being shown as normally held in troughforming position by a sprin clip 52 secured to the rear wall of the con nit 21 and hav ing a latch portion 53 at which it interlocks with a lug 54 on the troughsection 26.

- Referring to the construction shown in Figs. 7 and 8. this construction embodies the conduit which opens at its top and bottom into the room, the air-forcing device, the lower trough section forming a continuation of the rear wall of the conduit and the sec- .fore the same designatlng numerals have been applied thereto.

This construction differs from the one of the preceding figures in that, instead of pro-' 'viding the humidifying or cooling means for the air as shown in'th1s receding construction, means areprovi'ded wardl in the con uit sprays of either heated or coo water, de ding on whether the app aratus is to be used in the winter or summer.

he spraying means shownwomprise a pipe 55 located in the conduit directly above, and

in close proximity to, the trouglr26,thisp ipe being'provided at its ends with spray nozzles 56 preferably diverging upwardly as shown for-spraying upwardly in the conduitintersecting spray streams of water which for directing up impinge against-all sides of the conduit 21.

The pipe 55 is connected between its ends with a pipe 57 which corresponds with the pipe 43 and leads from a water strainer in communication with a water supply pipe represented at 58, as in the case of the constguction of the preceding figures, the flow 0 water from the pipe 58 to the pipe 57 being controlled by a valve as in the case of the preceding construction.

conduit 21 by the action of the fan 31 contacts with the sprayed water issuing from the nozzles 56 resulting in the heating, cleansingand' humidifying of the air when the It will be understood from the foregoing. that the air forced upwardly through the water is supplied in heated condition and i in the cleansing and cooling of the air when the water is supplied in cool condition,.it

being observed that by directing the water spra upwardl in the conduit and thus in the irection o the natural flow of heated air in the conduit the air is subjected to the action of the water-much more effectively than in the case where the water is sprayed in the reverse direction only and the possibility of frelatively large articles of water becoming entrained with t e air and discharging into the room. is greatly minimized.

It will be noted that in the spraying of the water as' stated. the air is not only subjected to the rising spray but also to a descending spray comprising such of the water as does not become entrained, in its upward movement. in theair whereby the apparatus is rendered not only very effective but economical in operat on.

Such of the water as does not become entrained 1n the air flows into the troughs 26 and 23, the water flowing from the latter -17, whereby this trough,

endwise thereof into the trough 23 and thence through the drain outlet.

. If desired, the trough section 26 instead of being hinged to the casing section 25 may be connected with, and $11 ported by, the door y the single act of opening the door 17, may be swung out of operative osition to permit of access to the parts of tie apparatus which would otherwise be obstructed thereby. Such arrangement is shown in Fig. 9 wherein it will be noted that the trough 26 is connected with the door 17 by a bracket member 59 and thus swings therewith.

Referring to Fig. 10 of the drawin s, the construction therein shown is provide as an apparatus intended for location in a portion of a building remote from the room, or rooms, to be suppl3ed with heated and humidified air, or cool air, as the case may be, as for example in the basement of a building.

The apparatus shown comprises a casing 60 for supplying conditioned air to a room 61 of a building located thereabove.

opening communicating with the lower end of a pipe 62 which opens at its 11 per, refcrably register-equipped, end t roug .an

. opening in the floor 63 ,of the room 61-, the

- the upper end of this pipe opening into the of this blower opening into the funnelroom 61 through an opening 67 in a wall 68 of the room. The pipe 62 serves to conduct air from the room 61 into the casing where it is conditioned, as hereinafter described, and the pi e 66 servesto convey the conditioned air or discharge into the room 61.

The casing 60 contains a hopper-sha ed casing 69 open at its upper end, at whic 1 it is preferably equipped with an air filter represented generally at 70, as for example in the form of a single sheet of filtering paper or amass of mineral wool, as is-commonly used, the upper end of the casing 69 bein thus in communication with ,the pipe 6 The lower end of the casing 69 opens into the inlet end of a blower 71 located in the bottom of the casing 60, the dischar e gig a inlet 72 of a conduit 73also located in the casing 60 and connected at its upper, outlet, end 74 with the inlet end of t e i 66. The lower portion of the conduit 78 is shaped to form a sump 75 from which leads 4 a drain ipe 7 6and the rear wallof the conduit at t e portion thereof against which the mam portion of the blast from the blower 71 impinges, curves rearwardly and upwardly as represented at 77. the conduit 73 at-the ortion 77 thereof being provided with a coil 78 for circulation therethrough of a heating or cooling medium, as desired. 4

Located between the upper and lower ends of the conduit 73 is a trough 79 extending The fl casing 60 is provided in its top Wall with an' crosswise of the conduit 7 3 ends thereto as explained of the trough 26 of the preceding figures of the drawings, this trough being so dis osed, as shown, that the air delivered by t e blower 71 impinges against its curved undersurface and is thus deflected and guided thereby toward the rear side of the conduit 73.

Located directly above the trough 79 are means for upwardly spraying water either heated or cool, into the conduit 73' into a position in which it is contacted by the air flowing upwardly through the conduit 73. The means shown comprise one or more spra nozzles 80 (a plurality thereof being pre erably provided and dis osed as in the case of the nozzles 56 in F igs. I and 8), the nozzle, or nozzles, as the case may be, being connected with a pipe 81 which would lead to any suitable source of water under pressure. The spray means are preferably provided with valve means, such as that represented at 82, for controllably regulating the ow of water from the pipe 81 to the nozzle, or nozzles, 80, the nozzle structure being preferably provided with valve nieans, the stem of which is represented at 83-for controlling the character the stream of spray nozzle constructions.

liminator plates shown as arranged in parallelism and located adjacent the outlet 74 of the conduit 73, are also provided to function as in the case of the; plates 22 of F ig. 3. These eliminator plates, represented at 84, are shown as pivotally supported at 85 on the wall of the conduit 73, with their upper ends connected together by a link 86 pivoted thereto. An arm 87 is connected wlth one of the pivots 85 and pivotally connects at 88 with the inner end of a slide rod 89 extending through the casing 60 to be accessible for operation from the exterior of the casing.

It will be understood from the foregoing that the air in flowing upwardly in the con duit 73 is subjected to the cooling, or heating, effect, as the case may be, of the coil 78 and thence passes upwardly through the water as is common in spraypray which removes dirt from the air humidcharged from the water-spraying means as does not become entrained in the air flowing in the conduit 73, flowing into either the trough 79, orsump 75, the water which flows into the trough 79 discharging therefrom into the sump.

Preferably means are provided for preventing water which may collect on the rear and related at its vBo of the spray and the spread of ing the rear wall ofythe-conduit above the 90 is a blower 92 shown as operated by an eleccoil 78 as represented at 73" to cause such deflected portion to extend forwardly of the lower endof the coil, whereby water dri ping from the lower edge of the conduit wal -portion 7 3 drops clear of the coil.

The construction shown'in Figs. 11 and 12 is designed primarily as a unit to be shifted.

from one location to another, as for' example from oneroom to another as in the case of a hospital, where it is desired to supply a room, or rooms, with cleansed air, in some cases humidified and heated, and in other cases cooled.

. This construction as shown comprises a casing 90 mounted on casters 91 permitting it to be rglled from one location to another as desire Mounted in the lower portion of the casing tric motor 93. The blower shown is of the centrifugal type containing inlets at its opposite sides which open into the casing 90, the latter being provided at its lower ortion with inlets 94 for the, air to be conditioned, the inlets being preferably screened as represented at 95 as for example by relatively fine wire mesh.

The outlet 96 of the blower is connected with a pipe 97 which opens at its upper, elbow, portion 98 through an opening 99 in an upwardly extending conduit 100 located in the casing 90, the upper end of this conduit, which is in the form of an elbow as represented at 101, communicating with an outlet opening 102 in one of the side walls of the casing .90 for discharge from the casing of the air conditioned as hereinafter explained, the outlet of this conduit being preferably screened, as by fine wire mesh represented at 103. The upper end of the conduit 100 preferably is equipped with eliminator platesrepresented at 104 constructed and regulated as ex plained of .the plates 84 in the construction shown in Fig. 10.

The casing 100 contains an upwardly. and

' rearwardly curveddefiector plate 105 extendingl crosswise thereof and op osite the outlet en of the pipe 97 against w ich the air discharged through this pi e by the blower 92 im inges there y-bein eflected upwardly.

ocated above the eflector plate 105 is a trough 106 connected with the front wall of the conduit 100, the ends of the trough 106 being related to the. adjacent sides of the conduit 100 as explained of the construction of the preceding figures of the drawings. The trough 106 IS spaced at its rear edge from the 11 per end of the conduit 105 thereby V provi m an air assage between these parts.

Locate direct y above'the trough 106 are means, represented generally at 107, for upwardly spraying watereither heated or cool,-

as conditions require, the construction of which may be the same as that described of the structure shown in Fig. 10. The pipe for supplying water to the spraying means 107 is represented at 108 and is shown as connected with the outlet of a pump 109 shown as operated by the shaft of the motor 93, the inlet 110 of'the pump 109 being connected with a pipe 111 which opens into the closed bottom portion of the conduit 100.

The apparatus now being described operates'substantially the same as that disclosed in Fig. 10, such of the water as does not become entrained in the air flowing in the conduit 100, gravitating into. the lower portion of the conduit 100 from which it flows into the pump 109 and is returned to the spray means 107, the lower closed portion of the conduit 100 forming a receptacle for water the supply of which therein may be replenished from time to time as the supply thereof becomes diminished by its entrainment in the air and discharging from the easing 90.

Preferably the apparatus also comprises a heater device represented at 112 disposed in the line of flow of the air to the inlet of the blower for heating the air, this device in the construction shown being represented diagrammatically as an electric heater.
